Buggy code:
public class ZipArchiveInputStream extends ArchiveInputStream { private static final int SHORT = 2 ; private static final int WORD = 4 ; private final ZipEncoding zipEncoding ; private final boolean useUnicodeExtraFields ; private final InputStream in ; private final Inflater inf = new Inflater ( true ) ; private final CRC32 crc = new CRC32 ( ) ; private final byte [ ] buf = new byte [ ZipArchiveOutputStream .

Fix:
inB = ZipUtil . adjustToLong ( inf . getTotalIn ( ) ) ;
